Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a robotic surgical system uses both laparoscopic and trans-cervical robotic arms with multiple tools, then the versatility and precision of tissue resection is improved, but the device complexity increases
Solution Approach 1:
The robotic system is divided into separate functional modules: a first robotic arm for trans-cervical access carrying resecting devices, a second robotic arm for laparoscopic access carrying ultrasound transducers, and a controller integrating their operations. This segmentation allows each module to be optimized independently while maintaining overall system versatility.
Solution Approach 2:
The robotic system employs multi-functional robotic arms that can carry and operate different types of surgical tools including resecting devices, endoscopes, and ultrasound transducers. The controller is designed to coordinate multiple tools and imaging devices, enabling a single system to perform diverse surgical functions through both trans-cervical and laparoscopic approaches.
2Measurement precision
If the system provides real-time ultrasound imaging and controlled tissue manipulation, then the measurement precision and safety are improved, but the device complexity increases
Solution Approach 1:
The system merges ultrasound imaging capabilities with robotic tissue manipulation by integrating ultrasound transducers into the robotic arm or positioning them in close proximity. The controller synchronizes the imaging and resection operations, allowing real-time visualization of tissue boundaries and resection progress without requiring separate independent systems.
Solution Approach 2:
The system implements real-time feedback by using ultrasound imaging to continuously monitor tissue location and resection progress. The controller receives ultrasound data and uses it to adjust robotic arm positioning and resection depth, ensuring precise tissue removal while avoiding damage to surrounding structures. This closed-loop control enhances measurement precision and safety.
3Manufacturing precision
If the resecting device performs axial and rotational movements for controlled tissue resection, then the manufacturing precision of resection is improved, but the device complexity increases
Solution Approach 1:
The resecting device incorporates dynamic movement capabilities with multiple degrees of freedom, including axial movement along the tool shaft and rotational movement around the longitudinal axis. The robotic arm provides dynamic positioning and orientation control, allowing the resecting device to adapt its position and angle in real-time during the procedure, achieving precise tissue resection through coordinated multi-axis movements.
